Wireless LoRaWAN gateway with 30 W solar panel

Milesight SG50-L08GL-868M is an energy-efficient outdoor 8-channel solar-powered LoRaWAN® gateway, designed for building IoT infrastructure in locations where access to the power grid and wired Internet is limited. Variant 868M supports, among others, the European EU868 plan, while the L08GL provides backhaul through global networks 4G LTE Cat.1 / GSM. In packet forwarder mode, the gateway can support approximately 2000 LoRaWAN® Class A/B/C devices, while the built-in Network Server enables local management of up to 100 devices and data integration via MQTT.

The standard SG50 configuration uses 30 W solar panel and an internal 3,6 V / 25 000 mAh, which according to the manufacturer can provide up to 4 days of typical operation without sunlight. The gateway offers external LoRaWAN®, LTE/GPS and 2,4 GHz Wi-Fi antennas, configuration via Web, MQTT API, Milesight Development Platform and DeviceHub, and OpenVPN Client. The aluminium enclosure IP67 operates at temperatures from −30 to +70°C, while the device can be mounted on a wall or pole.

Milesight SG50-L08GL-868M — solar LoRaWAN® gateway with 4G communication

Milesight SG50-L08GL-868M is an outdoor, 8-channel LoRaWAN® gateway designed to create autonomous IoT infrastructure in locations where providing permanent power and a wired Internet connection is difficult.

The device combines LoRaWAN® 868 MHz, modem 4G LTE Cat.1 / GSM L08GL, built-in 25 Ah battery and solar power. The standard SG50 configuration uses 30 W solar panel, and the manufacturer also offers an optional 45 W variant.

With an IP67 degree of protection, operating temperature range from −30 to +70°C and wall or pole mounting capability, the SG50 is suitable for distributed field installations, agriculture, water management, environmental monitoring and other systems requiring independent LoRaWAN® infrastructure.

Autonomous LoRaWAN® infrastructure powered by solar energy

Standard 30 W panel

Solar energy powers the gateway and simultaneously charges the internal battery.

25 Ah battery

The built-in backup power system keeps the device operating at night and during periods of limited sunlight.

LoRaWAN® + LTE

Data received from LoRaWAN® sensors can be sent to the higher-level system over the LTE Cat.1 cellular network.

Standard 30 W solar panel

The SG50 works as standard with a 30 W solar panel, which powers the device and charges its internal battery under suitable sunlight conditions.

The energy management system dynamically adjusts the charging current to the battery temperature to use available solar energy efficiently.

For installations requiring more available power, the manufacturer offers an optional SP1545 15 V / 45 Wfunction.

8 channels and support for approximately 2000 devices

The SG50 has 8-channel LoRaWAN® concentrator operating in half-duplex modefunction.

In packet forwarder mode, the gateway can support approximately 2000 Class A/B/C devices, although the actual number depends on uplink and downlink communication intensity.

Receiver sensitivity reaches −140 dBm at 292 bps, while the maximum transmit power is 27 dBmfunction.

Variant intended for operation under the European EU868 plan

Variant SG50-L08GL-868M supports the European EU868function.

The SG50 platform also supports other regional LoRaWAN® plans, including IN865, RU864, US915, AU915, KR920 and AS923.

For installations in Poland, the device should be configured according to the EU868 plan.

Integration with popular LoRaWAN® Network Servers

The SG50 can operate as a packet forwarder and forward received LoRaWAN® packets to an external Network Server.

Supported solutions include, among others, Semtech UDP Forwarder, Basic Station TCP Forwarder, ChirpStack v3/v4, Milesight Gateway Embedded NS, DeviceHub LNS and Milesight Development Platform LNSfunction.

Advanced functions include Packet Filter, Listen Before Talk and Data Retransmissionfunction.

Local support for up to 100 LoRaWAN® devices

The SG50 has built-in LoRaWAN® Network Server, allowing it to operate without an external LNS in selected installations.

The built-in server supports LoRaWAN® V1.0.3 Class A/Class C and up to 100 devices.

Data integration with the higher-level application can be performed via MQTTfunction.
